Roof Void Automatic Cluster Fly Control Pack

Had an infestation of cluster fly in the outlet flu of my oil boiler cupboard in a ground floor shower room. The dispenser was easy to assemble and within a couple of days the results were excellent. On my second canister, the first one lasted approx 3 weeks. The problem appears to have gone. Quick and easy just set the time, turn it on and let it do the work.

Excellent product, does exactly what was described. It has completely cleared our roof void of "an invasion" of cluster fly in two months of treatment, operating from dispenser spray every 15 minutes, 24 x 7. If your home is surrounded by large lawns, or grassy meadows, this type of location provides the ideal environment for cluster fly invasion of roof voids from September through April.

The nozzle is very easily misaligned with the spray can - usually stops working after a week or two, and has to be readjusted.

Clears away attic flies gradually , but cannot get refills hence the rating

Recently moved into new offices and the roof void was infested with cluster flies, we used a "bomb" for initial removal and have used this product to get rid of the stragglers, it has worked brilliantly, each day for a week or so, we found fly corpses but they have now gone completely, highly recommended

Arrived this week and installed in our loft. Despite a large number of fly clusters already there, the dispenser has done an amazing job of controlling the fly numbers and we now have reclaimed our loft.

Has done the trick and canisters last as long as they say. Good buy

Worked well.
